Anyone from the era when we had to bash typewriters will have had a small bottle to hand. If you were as bad a typist as I am, you needed it in industrial quantities.

That’s the brand I remember, because that was the product my college bought (and I could thieve from the cupboard). And — strewth! — didn’t over-indulgence (i.e. mine) clog up any typewriter.

So, one Friday evening, recovering from a hard week at the chalk face, I was into my second, or even third pint of Courage Directors (not yet a Charlie Wells brew). My location was the John Baird, Muswell Hill. Now, three pints at 4.6% ABV ought to have some effect, especially when imbibed against the clock (the Lady in my Life would be doing Sainsbury’s shop down the road). If you like, this was my six-o’clock swill.

Suddenly the side door from Prince’s Avenue opens to admit a bevy of very buxom belles (doubtless chosen for the parts). The white tee-shirts all boost the slogan: Sno-pake covers all your boobs.
